About
eight inches immediately below these ropes, and four feet from the
bottom of the car I fastened another shelf- but made of thin plank,
being the only similar piece of wood I had. Upon this latter shelf,
and exactly beneath one of the rims of the keg, a small earthern
pitcher was deposited. I now bored a hole in the end of the keg over
the pitcher, and fitted in a plug of soft wood, cut in a tapering or
conical shape. This plug I pushed in or pulled out, as might happen,
until, after a few experiments, it arrived at that exact degree of
tightness, at which the water, oozing from the hole, and falling
into the pitcher below, would fill the latter to the brim in the
period of sixty minutes. This, of course, was a matter briefly and
easily ascertained, by noticing the proportion of the pitcher filled
in any given time. Having arranged all this, the rest of the plan is
obvious. My bed was so contrived upon the floor of the car, as to
bring my head, in lying down, immediately below the mouth of the
pitcher.
